yes, that is correct. he can end it anywhere in the middle east if he starts from cairo.

And the global explorer (34k) are the same prices as the four continent oneworld explorers. You only have three continents so the oneworld explorer would actually be cheaper without sacrificing much given the routing you have proposed. I would personally either drop Hawaii or just buy a seperate ticket there. Unfortunately, You can't visit Hawaii without also going through/visiting Sydney becasue 1) you can't back track to the US (which is what you have done) and 2) becasue you can't do an open jaw across the pacific ocean by buying a ticket from somewhere. If you go to Sydney then obviously you blow your mileage limit on the global explorer so that's out. Then youre left with having to buy a 4-continent ticket. Given the circumstances, it makes more sense to me to either just buy a ticket from Los Angeles, which routinely run $300-500 in coach, or to use miles to get an award ticket. The last option is just to drop it. If you want to go to a nice island then go to one of the Thai islands, Bali, one of the Malay islands, or a whole host of others. Canaries are another option as well as all the other Spanish and portuguese islands. For that matter, youre close enough to Zanzibar to probably make the trip for a reasonable price though obviously not on this ticket.
